To a. whont it may concern:

Be it known that I, EUGENE PAUL ALFRED VILLETTE, engineer, of 2 Boulevard Bigo Dane], Lille, in the Republic of France, have invented Improvements in Means for Stopping the Motion of Vessels, of which the following is a specification.

The present invention has for its object an arrangement of telescoping plates arranged vertically and grouped together in sufficient numbers and level with the hull of the vessel below the water-line.

By way of example, this improved system is represented in the accompanying drawings, in which Figure 1 is aplan of a vessel provided with this invention, the plates being shown as projected. Fig. 2 is a side view of the same. Fig. 3 is a view, on a larger scale, of two adjoining plates. Fig. 4 is aview, on the same scale and in section, of a telescopic plate when not in usethat is to say, flush with the hull. Fig. 5 is aview of the same plate, shown projecting to effect the stopping or maneuvering of the vessel. Fig. 6 shows a plan of a modification of the preceding figures.

As shown in the figures, the plates are placed in groups aalong the hull b of the vessel, Fig. 1. They are arranged alternately or zigzag, so as to present a large resistingsurface to the fluid current formed by the speed of the vessel. The plates consist of two parts 0 and (Z, fitting and telescoping into each other, and they are arranged in the hull bso that they projectnorrnally perpendicularly to the longitudinal axis of the vessel. The part 0 is held in the part (Z by means of projections e at the back, which abut against the interior shoulders f, formed by the hollow part d. Stops g are made in the interior of the back end of the parts cl in order to limit the movement of the flat plates 0 in the hollow parts a]. These plates or parts 0 and (Z are arranged vertically in the hull dot the vessel, so that they can slide with little friction, and for this purpose they are subject to a perfect amount of lubrification obtained as follows: A hole Z is made in the casing 7t and brings the oil between the casing and the plate (Z, whence it penetrates by a hole m above the plate c. When the plate 0 is brought out from the interior to the exterior, the oil is .then driven through an and a to the bottom of the casing, whence it is distributed under the plate (Z and that 0 by the passages or holes 0 and 10.

Inside the vessel and behind each plate is fixed a tight metal casing it, which serves as a guide to the plates cand (Z. The bottom of this casing forms inside projections '6, against which the plate (Z presses when at rest, Fig. 4. These projections have for their object to pre vent too much adherence of the plate (Z against the bottom of the casing and also to allow the passage of the actuating agent compressed air-which is introduced into the casing at the opening is, whence it penetrates behind the plate 0, which is pushed out and draws with it by the books 6 the surrounding casing (Z against the shoulders f. The compressed air necessary for this operation is supplied by a special machine, the distributing valves or cocks of which are brought to a point conveniently accessible to the commanding officer or the ofiicer of the watch. The plates having produced their effect in stopping the vessel are brought back to their closed position by the opposite action to that used for driving them outthat is to say, by a vacuum made behind them in the casings It.

It is obvious that each group of the retarding-plates will have its special regulatingvalve under the control of the officer in charge, so as to enable him to operate the whole or part of the apparatus whether for stopping or maneuvering the vessel.

Fig. 6shows in plan and in section a modification of the arrangement described above in which the retarding-plate r is made in the shape of a quarter of a circle and is jointed to the hull 6. Inside the hull this plate is contained in a tight casings with an opening and pipe at t for introducing compressed air to force out the plate or for withdrawing the air to bring back the plate into 8.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In apparatus for quickly stopping vessels in movement, plates consisting of two sec tions telescoping into each other when at rest and arranged vertically in zigzag form and in group along the length of the hull of the vessel: the inner section having projections and the outer one stops to limit the movement of the interior one: and the outer plates having projections adapted to abut against the wall of the hull for the same purpose, substantially as described.

2. In apparatus for quickly stopping vessels in movement, plates consisting of two sec- TOO tions telescoping into each other when at rest and arranged vertically in zigzag form and in groups along the length of the hull of the vessel, the inner section having projections and the outer one stops to limit the movement of the interior one, and the outer section having projections adapted to abut against the wall of the hull for the same purpose, in combination with a casing for each telescoping plate,

IO in which casing said plate is adapted to operate as described and means for admitting an operating fluid into and withdrawing it from the casing to effect the operation of the plate.

In testimony whereof I afiix my signature in presence of two Witnesses.
